book arrived today. i looked through it and found heaps of info on electrical circuits, formulas (ohms law) and other things electrical. i studied broadcast engineering in college, so i do not need a cream of wheat review of basics. from the look inside, as well as the hoohah on the front and back cover, i expected a few projects to be presented in detail. there is zero of that presented.i recommend buying any other book on solar projects than this one.
when i open up the book, the first page that i see is the last page of the book and it is upside down.when i open up the back pages, i see the conclusion printed upside down.the book can be read if; you hold the book upside down and read it back to front.one could say this book is usd abw's.i wonder how many 1000's have been printer like this?
this book does not contain any useful information. it appears cobbled together from things copied off the internet. the book does not even have an author. about half the book contains information so obvious that it would not be useful to even someone who understands nothing about electricity. the information about grounding electrical systems is incorrect and potentially dangerous. it's shocking that anyone would have wasted their time putting this together.
